Sen. Elizabeth Warren slammed President Donald Trump on Twitter on Friday after the commander-in-chief revived his often-used taunt for the Massachusetts Democrat and called for an FBI investigation into the Democratic National Committee.

Pocahontas just stated that the Democrats, lead by the legendary Crooked Hillary Clinton, rigged the Primaries! Lets go FBI & Justice Dept.

Trump’s tweet referenced statements Warren made to the media Thursday, saying she believes the Democratic National Committee was rigged in favor of candidate Hillary Clinton during the 2016 presidential primaries.

Donna Brazile, the former interim acting chair of the DNC, detailed in book excerpts published by Politico how the Clinton campaign helped the DNC, which was in “significant debt” financially.
